BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container, and more specifically, a stick-shaped body such as lipstick is housed in a case which is rotatable and moved up and down, and the stick-shaped body is projected without separating from the case during use. The present invention also relates to a container that can be put back in the case until the next use.

2. Description of the Related Art A conventional container comprises a rod-shaped holding cup that can slide axially in two concentric coaxial sleeves that rotate relative to each other, and the outer sleeve is fixed and the inner sleeve is It is a rotary type. On the inner surface of the outer sleeve, two spiral grooves are symmetrically cut 180 ° apart. The rotatable inner sleeve has two symmetrical longitudinal slots at diametrically opposite positions, each slot having a 90 ° bent recess at each end of travel of the cup. The recess faces away from the rotation of the sleeve that guides the cup to its end of travel. The cup has two outwardly projecting nipples spaced 180 ° from each other, each nipple penetrating a slot and the tip reaching the spiral groove.

From a cosmetic and economic standpoint, such container features are usually manufactured from thin-walled materials such as plastics. Although plastic has good mechanical strength and is suitable for normal use, it is not strong enough to prevent the neck of the nipple from coming out of the slot when excessive twist is applied at the end of travel of the cup. There are cases. If the nipple happens to come off in this way, it will have an adverse effect on the next use. In order to eliminate this drawback, the thickness of the inner and outer sleeves is increased to the maximum that the diameter of the container is commercially acceptable, and at the same time, there is a disadvantage in terms of appearance and economy, and measures must be taken against them. I won't.

SUMMARY OF THE INVENTION An object of the present invention is to solve the drawbacks of conventional containers and to provide a container in which the rotating mechanism cannot be accidentally removed even when a thin sleeve is used.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a container as described above for use with rod-shaped materials, wherein the width of the spiral groove matches the width of the top of the nipple and is greater than the width of the recess, and the nipple is It has a constriction cut symmetrically in a position facing the inner sleeve, and the constriction has a length corresponding to the thickness of the inner sleeve and a depth corresponding to a space corresponding to the width of the recess, whereby The nipple slides easily in the spiral groove, the slot and the recess with little play and at least in the recess captures the opposite edges of the wall of the inner sleeve with a slight frictional force.

The longitudinal slot can be as wide as the recess, in which case the neck of the nipple can be circular and the longitudinal slot can be of the same width as the spiral groove, in which case the neck of the nipple can be made. Is a notch parallel to the direction of the recess.

The outer edge of the wall of the inner sleeve can be chamfered at least at the end of the recess to more effectively press the nipple against the inner surface of the wall to facilitate entry of the nipple into the recess. The recess corresponding to the storage position of the rod-shaped body in the container may be formed by chamfering the outer edge of the vertical slot end.

In order to prevent the disengagement more effectively, an auxiliary stopper is provided on the inner sleeve and the outer sleeve to limit the relative rotation between the sleeves to one rotation or less and to forcibly set the moving end point of the cup. You can also

For a more detailed understanding of the present invention, the following description will be made in detail with reference to the accompanying drawings, in which a small number of embodiments can be easily conceived by those skilled in the art. It is only a matter of choosing an embodiment. Corresponding members are designated by the same reference numerals in these drawings. The dimensions of these parts and their proportions have not been taken into account in order to make the drawing easier to understand.

The case for a rod-shaped substance such as lipstick shown in FIGS. 1 to 4 basically has a cup 1 for holding a rod-shaped body 2. The cup 1 has two nipples 3 and 3 ′ projecting outward at diametrically opposed positions, and the tip of the nipple is concentric with the outer sleeve 5 and an inner sleeve that rotates in the opposite direction. 7 through the longitudinal slots 6, 6'and slide in the opposite spiral grooves 4, 4'which are symmetrically cut into the inner surface of the outer sleeve 5. At the end points of the movement of the cup 1, the slots 6 and 6 ′ are recessed by the recesses 8, 8 ′, 9 and 9 ′ which are bent 90 ° in the direction opposite to the rotation direction of the inner sleeve 7.
, Which leads the cup 1 to its end of travel.
The outer jacket 10 is optionally decorated and covers the outer sleeve 5.

The tops 11, 11 'of the nipples 3, 3'are
It is slightly smaller in width than the spiral grooves 4, 4'and freely slides therein, but wider than the recesses 8, 8 ', 9, 9'. Constrictions 12, 12 'are cut symmetrically in the nipples 3, 3'facing the wall of the inner sleeve 7. The length of the constriction is slightly larger than the thickness of the inner sleeve 7, and the depth is the recesses 8, 8 ', 9,
Slightly smaller than the width of 9 '. In this way, the nipples 3, 3'will have slots 6, 6'and recesses 8, 8 ',
It penetrates through 9 and 9'and freely slides in the grooves 4 and 4'with little play, and captures the edge of the opposing inner sleeve 7 by a slight frictional force in the recess at the end of each movement of the cup 1. To do. This avoids the risk of the nipple coming off the recess.

The constricted portions 12, 12 'are formed in the concave portions 8, 8',
The outer edges of the wall of the sleeve should be 13, 13 ', 14 (Figs. 2, 5 and 6) to ensure secure insertion within 9, 9'.
It can be chamfered as shown in.

In another embodiment shown in the lower part of FIG.
The recess is transformed into a chamfer 14a at the end of the slot 6a, which catches the wall of the sleeve 7a in the constriction of the nipple 3a and fixes the cup at its lowest point. In this position, the cup and rod are returned to the case, and the other end of the cup does not receive the force of pushing the rod out of the case and pressing it against the surface. At the other end point mentioned above, it is preferable to extend the slot into a lateral recess having a length at least equal to the diameter of the nipple 3 to fix the cup axially.

7 and 8 show another embodiment of the present invention, in which the constricted portion of the nipple 3b is recessed 8b, 8b.
It consists of two notches 12b, 12b 'parallel to the axis of b'. The distance between the cutout surfaces of the nipple is slightly smaller than the width of the recess into which the nipple fits.

It is effective to provide a stopper 15 at one end of the sleeve 5c having a spiral groove in order to more reliably prevent the rotation of the cup at each end of its movement. The stopper is a sleeve 7c having vertical slots (Fig. 10,
It works in cooperation with another stopper 16 at the corresponding end of 11). The width of the stoppers 15 and 16 limits the relative rotation of the sleeves 5c and 7c to slightly lower than one rotation, but this does not cause any practical problem in the lipstick case.

[0016]

Industrial Applicability According to the present invention, it is possible to provide a rotary container for a rod-shaped substance which is excellent in practicability and which is free from the risk that the rotary mechanism will come off even if a plastic material is used.
